FluentFTP: Incorrect retry actions after transfer connection drops because server reports too long file size

FTP Server OS: Apache FtpServer

Client Computer OS: Ubuntu (amazon linux 2)

FluentFTP Version: 42.0

Framework: .NET 6

It is working very few time under Ubuntu, but under Windows I got a file with double or 3x size.
